f2fs-tools fails to cross build from source, because its upstream
build system wrongly uses AC_CHECK_FILE. The purpose of the macro is
checking for files on the host system. However here it is used to
check whether a .git directory exists, which is a property of the
build place. A simple "test -d" should be used here. After doing so,
f2fs-tools cross builds successfully.

f2fs-tools uses ioctl BLKSSZGET to get sector_size, however, this ioctl
will return a value which may be larger than 512 (according to the value
of q->limits.logical_block_size), then this will be inconsistent with
the start_sector, since start_sector is got from ioctl HDIO_GETGEO and
is always in 512 size unit for a sector. To fix this problem, just
change the sector_size to the default value when computing with
start_sector. And fix sectors_per_blk as well.

This patch introduces lost_found feature to fsck. If a file is found
unreachable by fsck. Fsck tries to reconnect the file to lost+found
directory:
1. Scan all unreachable file inodes, ignore non-inodes ones and
directories.
2. Check them and fix incorrupted data to make sure filesystem
metadata (mainly counters and main/nat bitmap) are all consistent.
3. Reconnect these files to lost+found. If lost+found does not exist,
create it first. During reconnecting, expand lost+found's dentry
block automatically. Reconnected files are renamed after its ino
number.
4. If reconnect fails drop the node and restore filesystem metadata.
